The definition of Post Herpetic Neuralgia (PHN) has been a matter of discussion for a long time, being defined at different time intervals after rash healing in herpes zoster. PHN has been defined as pain persisting or resuming 4, 6, 8, 12 weeks, or even 6 months after rash healing1. Post herpetic neuralgia affects nerve fibers and skin, causing burning pain that lasts long after the rash and blisters disappear.

The risk of post herpetic neuralgia increases with age, primarily affecting people older than 60. There's no cure, but treatments can ease symptoms2.

If you are effected by Post Herpetic Neuralgia, you may qualify for a research study currently assessing the safety and efficacy of a new medication designed to treat this condition.

Qualified participants will be compensated for time and travel. Study medications and study related care are provided at no cost, without the need for health insurance.

Help us discover new treatments and ease the discomfort experienced by so many. Take a moment to volunteer by completing the form below.

A Study Volunteer Specialist will contact you when a study fitting your interest is available.
